The programs =TEIF, MOMITOR, and [L105 give you the option to call a user-written conversion
program. You can use a conversion program to change a measurement obtained from the HP 3421 A Data
Acquisition/Control Unit into more useful units. Conversion programs are written as BASIC subprograms
which are called after a measurement has been taken, but before any limit tests are taken (if applicable).
D.1 STRIP AND MONITOR CONVERSIONS
The "THEIF and MOMI TOR programs call the conversion program passing a single measurement. The
syntax for a conversion program header is:
=lIE
subprogram-name'. numeric variable:
Program example:
1a
SUE STEAIMCS
SE
OS=CSs ITER] ARSE ES sR
20
EMD SUE
This is the simplest form of a conversion program.
A number is received, altered through an equation,
and returned to the calling program.
More complex conversion programs might evaluate a polynomial
solution, do a table look-up, etc.
D.2 LOG CONVERSIONS
The L115 program calls the conversion program passing a vector of raw measurements and the number of
measurements to be converted. The syntax for the conversion program header is:
=IIE subprogram-name'. vectors numeric variable
Program example:
1a SLE STREAIMHLCORS 3, C0
ZB FOR I=1 TO C
SE RCI s=RCIy1S, 2504S
FE HEST I
pS 0 =
This is the simplest form of a conversion program for the |.IJl5 program.
As in the example above, the
conversion might be more complex.
